Narrowband auscultatory blood pressure measurement

D.J. Sebald, D.E. Bahr, A.R. Kahn
2002 IEEE Transactions on Biomedical Engineering  
Auscultatory blood pressure measurement uses the presence and absence of acoustic pulses generated by an artery (i.e., Korotkoff sound), detected with a stethoscope or a sensitive microphone, to noninvasively  ...  The acoustic noise, on the other hand, appears in both microphones simultaneously.  ...  Van Veen, "Application of MVDR beamforming to reject turbulence noise in a duct," in Pr oc.

Performance of optimized sound field control techniques in simulated and real acoustic environments

Philip Coleman, Martin Møller, Martin Olsen, Marek Olik, Philip Jackson, Jan Abildgaard Pedersen
2012 Journal of the Acoustical Society of America  
The aim of this study was to explore the effects of original and modified intensive care noises on sleep in 15 healthy subjects.  ...  Test results showed that substitution of a hard surface flooring material for carpeting resulted in a net increase in corridor noise levels with the expected patient and medical professional perceptions  ...  The MVDR beamformer with diagonal loading was designed to get the horizontal directivity pattern in frequency band of 1kHz to 3kHz.  ...

Application of the PE method to up‐slope sound propagation

Marta Galindo, Karsten Bo Rasmussen
1995 Journal of the Acoustical Society of America  
The control mn is used to estimate the ambient noise processes on long-term scales. Maps of the anthropogenic signal to the ambient noise ratio of the climate system can then be constructed.  ...  Use of simplified coupled mode propagation for the prediction of impulse responses of megameter trans-Arctic propagation paths. Herbert A. Freese (Sci. Applic. Int.  ...  This ratio is only 20 (between 0.5 and 10 cm 2) for the "compact" versus "diffuse" axis (from/a/to/i/).  ...

Effects of errorless learning on the acquisition of velopharyngeal movement control

Andus Wing-Kuen Wong, Tara Whitehill, Estella Ma, Rich Masters
2012 Journal of the Acoustical Society of America  
In that respect, several alternatives are discussed to represent the Herglotz density as a sum of a finite number of basis functions.  ...  In practical cases only a limited amount of information is available to compute the Herglotz kernel, typically because a finite number of sensors is used for the measurement.  ...  The LCMV deals with the more general case of multiple desired speakers. It is argued that the MVDR beamformer exhibits a tradeoff between the amount of speech dereverberation and noise reduction.  ...

Speaker comfort and increase of voice level in lecture rooms

Jonas Brunskog, Anders C. Gade, Gaspar Payà Bellester, Lilian Reig Calbo
2008 Journal of the Acoustical Society of America  
Degree of intensity dip has the strongest effect, with a minimal dip in intensity more likely to be perceived as 'kneel' and a strong dip in intensity more likely to be perceived as 'needle. ' The results  ...  Presence vs. absence of a dip in intensity, duration of that dip, and degree of that dip in decibels are manipulated.  ...  Near-field scattering of ducted fan noise using a boundary element method.  ...

Free‐field reciprocity calibration of laboratory standard (LS) microphones using a time selective technique

Knud Rasmussen, Salvador Barrera‐Figueroa
2006 Journal of the Acoustical Society of America  
Acknowledgment of Honolulu Local Meeting Organizing Committees Presentation of Fellowship Certificates  ...  A minimum variance distortionless response beamformer using dominant mode rejection was implemented, applied to both uniform and distorted array shapes.  ...  A generalization of the standard MVDR approach, called multirank MVDR, assumes only that the signal lies in a subspace of multiple rank rather than the usual rank-one assumption.  ...

This may also result in reduced sensitivity to the temporal fine structure of sounds.  ...  In extreme cases, the IHCs/synapses/neurons may be almost completely non-functional over a certain region of the cochlea, giving a "dead region".  ...  To optimally benefit from binaural unmasking and to preserve the spatial impression, several extensions for the binaural MVDR beamformer and MWF have been recently proposed, which aim to also preserve  ...
